When detecting the level of charge of battery 11, as F/s, battery 11 is full of electricity.Whether be 100% to judge whether battery 11 is full of electricity with charge volume.In addition, whether charge volume is 100% can to detect by the charge volume that utilizes watt meter instrumentation battery 11.
In F/s, for battery 11 is full of electricity, shown in Fig. 2 A, relay 21,22,23 is connected, relay 24 is disconnected.Thus, battery 11 is connected with alternating current generator 12 and charges.In addition, in this F/s, for charging to battery 11, limit the use of non-driving system Denso spare 13 on the spot.
For the battery 11 of new product, shown in the solid line among Fig. 3, SOC begins charging from the state of S1, and when t1 was full of electricity in the moment, SOC rose to S2.
With respect to this, for aging battery 11, shown in the dotted line among Fig. 3, SOC begins charging from the state of S1, even be full of electricity at moment t1, SOC also only arrives S2D(＜S2).
Then, as subordinate phase, for no matter how ageing state all makes the state consistency of battery 11, drive non-driving system Denso spare 13 and make the 11 discharge schedule times of battery.
The subordinate phase from moment t1 to t2, relay 21,23 is disconnected and under with relay 22,24 states of connecting (with reference to Fig. 2 B), making battery 11 discharges by the electric power that drives non-driving system Denso spare 13 consuming cells 11.
At this moment, for the battery 11 of new product, shown in the solid line among Fig. 3, SOC drops to S3 from S2.In addition, for aging battery 11, shown in the dotted line among Fig. 3, SOC drops to S3D(＜S3) from S2D.In addition, no matter battery 11 is new products or aging, during subordinate phase all is identical from moment t1 to t2.
So, as the phase III, battery 11 is charged.In this phase III, carry out the detection of level of charge.
In the phase III, with F/s similarly, for battery 11 is charged, shown in Fig. 2 A, relay 21,22,23 is connected, relay 24 is disconnected.Thus, battery 11 is connected with alternating current generator 12 and charges.In addition, in this phase III, for carrying out effectively limiting the use of non-driving system Denso spare 13 to the charging of battery 11.
Herein, the characteristic shown in the solid line among Fig. 3 is that battery 11 is the characteristic in the new product situation, the charging cumulant from the needed time of S4 that S3 rises to as predetermined charge state (SOC) be T1.Herein, time T 1 is the time from moment t2 to t3, and the difference of charging cumulant S3 and S4 is charge volume C1.
With respect to this, shown in the dotted line among Fig. 3, at battery 11 constantly under the aging states, because the charging spended time, when making the charging cumulant charge to predetermined charge condition S4 after dropping to S3D because of discharge, with spended time T2(T2＞T1).Time T 2 is the time from moment t2 to t4.Herein, the difference of charging cumulant S3D and S4 is charge volume C2, and C2 is greater than C1, but compares with T1, and T2 is considerable time.
So, the degree of aging of battery 11 larger (aging developing more), the time that the predetermined charge condition S4 of arrival uses is just longer.
Therefore, in the threshold value of setting charging duration and situation that charging duration is longer than threshold value, be judged to be battery 11 and be aged to and need to change or cautious state.In addition, battery 11 whether aging judgement by degree of aging detection unit 150(with reference to Fig. 1) carry out.
So, in embodiment one, judge the degree of aging (whether needing to change or examine) of battery 11 by measuring level of charge.
Then, use Fig. 4 A, Fig. 4 B to judge that to being used for the processing of degree of aging describes.
Fig. 4 A is that expression is by the diagram of circuit of the contents processing of degree of aging decision maker 100 execution of embodiment one.
The diagram of circuit of Fig. 4 B contents processing that to be expression carried out by the car-mounted device 200 that is equipped on the vehicle that the car-mounted device 200 that utilizes embodiment one monitors.
Shown in Fig. 4 A, degree of aging decision maker 100 at first sends decision instruction (step S 1) to car-mounted device 200.Decision instruction is generated by decision instruction generating unit 130, and is sent to car-mounted device 200 via Department of Communication Force 120 from degree of aging decision maker 100 by master control part 110.In addition, decision instruction for example per six months once such regular transmission get final product.
Then, degree of aging decision maker 100 determines whether the data (step S2) that receive the expression level of charge from car-mounted device 200.Master control part 110 receives the data that represent level of charge via Department of Communication Force 120, and obtains this data by level of charge acquisition unit 140.In addition, repeatedly carry out the processing of step S2, until master control part 110 receives the data of expression level of charge.
When receiving the data of expression level of charge from car-mounted device 200 (S2 is), degree of aging decision maker 100 is judged the degree of aging (step S3) of battery 11.The processing of step S3 is based on the data of the level of charge that expression level of charge acquisition unit 140 obtains and by degree of aging detection unit 150 charging duration and threshold time is made comparisons to be carried out.Result of determination is sent to master control part 110 from degree of aging detection unit 150.In addition, threshold time is so long as the time longer than the charging duration T1 of the battery 11 of new product shown in Figure 3 gets final product, and for example can set for than T1 has increased by 50% time.
In step S3, when being judged to be battery 11 when aging (being aged to needs to change or cautious degree) (S3 is), the data that master control part 110 will be used for the data that the notice warehouse-in urges and be used for changing the control of vehicle 10 are sent to vehicle 10(step S4A).
On the other hand, in step S3, when being judged to be battery 11 when unaged (S3, no), master control part 110 will represent that battery 11 unaged data are sent to vehicle 10(step S4B).
When the processing of step S4A or S4B finished, master control part 110 registered to (step S5) among the DB160 with result of determination.Herein, degree of aging decision maker 100 is owing to judge the battery 11 of many vehicles 10, thereby as long as registers result of determination with indications and the date time correlation connection ground of vehicle 10.
Then, with Fig. 4 B the processing of being undertaken by car-mounted device 200 is described.
Car-mounted device 200 determines whether from the degree of aging decision maker 100 as remote monitoring center and receives decision instruction (step S 11).The processing of step S11 is carried out by master control part 210, until receive decision instruction.
When receiving decision instruction (S11 is), car-mounted device 200 judges whether vehicle 10 is in idling mode (step S12).Under idling mode, because the speed of a motor vehicle is zero, so the speed that detects based on car speed sensor of idling mode detection unit 230 determines whether and is in idling mode.
When being judged to be vehicle 10 and being in idling mode (S12 is), car-mounted device 200 obtains congestion information (step S13).Herein, congestion information acquisition unit 240 is obtained the VICS information of vehicle 10 working direction.
Then, car-mounted device 200 judges whether idling mode continues (step S14).The processing of step S14 is carried out by lasting detection unit 250.
Continue VICS information exchange that detection unit 250 obtains based on congestion information acquisition unit 240 cross judges block up the interval whether as predetermined length with on judge whether idling mode lasting.
When being judged to be idling mode and not continuing (S14, no), car-mounted device 200 makes flow process turn back to step S13.Thus, the repeatedly processing of execution in step S13, S14 continues until car-mounted device 200 is judged to be idling mode.
(S14 when being judged to be idling mode and continuing, be), car-mounted device 200 is carried out the user of vehicle 10 is sent the confined notice of part of functions of non-driving system Denso spare 13, the hand-off process of electric system and the driving processing (step S15A) of non-driving system Denso spare 13.
The confined notice of part of functions of the user of vehicle 10 being sent non-driving system Denso spare 13 will represent by master control part 210 that the confined information of part of functions of non-driving system Denso spare 13 is shown on monitor of being shown in homing advice on the monitor 290 etc. and realize.The part of functions of non-driving system Denso spare 13 is limited such as being the volume of reduction acoustical equipment or the function of restriction homing advice etc.
The hand-off process of electric system is that relay 21～24(is with reference to Fig. 2 A, Fig. 2 B) hand-off process, when measuring level of charge, carried out by electrical path control part 260.
When detecting the degree of aging of battery, the driving of non-driving system Denso spare 13 is processed by driving instruction department 270 outputs and is carried out for the driving instruction that drives non-driving system Denso spare.For example, when detecting the degree of aging of battery, in the situation that drives air-conditioning, drive instruction department 270 and will drive the ECU that instruction is sent to air-conditioning, thus, utilize predetermined pattern (for example, defrosting mode) to drive air-conditioning.
The processing of step S15A is the processing of processing to measure level of charge by carrying out the driving that the user of vehicle 10 is sent the hand-off process of the confined notice of part of functions, electric system of non-driving system Denso spare 13 and non-driving system Denso spare 13.
In addition, parking period carries out under the idling mode because the processing of step S15A is at vehicle 10, degree of freedom when therefore forcing to drive non-driving system Denso spare 13 is higher than the occasion (with reference to step S15B) of carrying out in the process of moving same treatment, can carry out rapid discharge or fast charge.In addition, in the situation of parking period like this, also can constitute, the master control part 210 of car-mounted device 200 will be sent to be used to the instruction that drg is worked the ECU of the brake system of control vehicle 10 forcibly.
Then, car-mounted device 200 detects level of charge (step S 16).The processing of step S16 is undertaken by level of charge test section 280.Level of charge test section 280 detects the level of charge of battery.
Then, the detection among the car-mounted device 200 determination step S16 whether complete (step S17).
For example, in the testing process of the level of charge in step S15A, in the situation that vehicle 10 changes from idling mode to motoring condition, there is the possibility of the electric energy generated change of the power consumption of non-driving system Denso spare 13 or driving system Denso spare 14 or alternating current generator 12.Therefore, master control part 210 for example monitors the speed that car speed sensor detects, when occurring this situation that testing conditions changes the testing process at level of charge the situation about changing from idling mode to motoring condition such as vehicle 10, it is not complete to be judged to be detection, and flow process is turned back to step S12.
On the other hand, it is complete that master control part 210 is judged to be detection when such situation that the testing conditions that level of charge do not occur changes, and make flow process advance to step S18.
Car-mounted device 200 will represent that by Department of Communication Force 220 data of the level of charge that detected by step S16 are sent to degree of aging decision maker 100(step S18).The transmission of the data of expression level of charge is undertaken by master control part 210.
Then, when car-mounted device 200 receives result of determination from degree of aging decision maker 100, agingly judge (step S19) to what whether result of determination represented battery 11.The processing of step S19 is carried out by degree of aging detection unit 150.
Car-mounted device 200 is when being judged to be result of determination and representing battery 11 aging (S19 is), and the information of will the expression warehouse-in urging is shown on the monitor 290, and (step S20A) processed in the control change of the driving 10 of going forward side by side.It for example is the processing of the part of functions in the non-driving system Denso spare 13 of restriction that the control change of vehicle 10 is processed.In the situation that battery 11 wears out, be desirably in battery 1 close on the life-span (et out of order) before, safety and promptly vehicle 10 is moved to the docking facility or the place etc. of safety, therefore, by limiting the part of functions in the non-driving system Denso spare 13, can alleviate the load of battery 11, allow to mobile state and prolong as far as possible.In addition, the part of functions in herein the non-driving system Denso spare 13 is limited to refer to the air quantity restriction such as air-conditioning, the volume limitations of acoustical equipment etc.
On the other hand, car-mounted device 200 is shown to (step S20B) on the monitor 290 with expression battery 11 intact information when being judged to be result of determination and not representing battery 11 aging (S19, no).Thus, the user of vehicle 10 do not need the replacing of battery 11 or cautious in can identify between short-term.
In addition, in step S12, in the situation that is judged to be vehicle 10 and is not in idling mode (S12, no), car-mounted device 200 makes flow process advance to step S15B.Being judged to be the situation that vehicle 10 is not in idling mode refers to: the speed of a motor vehicle is non-vanishing, and vehicle 10 is in the situation of motoring condition.
Even vehicle 10 is in motoring condition, car-mounted device 200 also the processing of execution in step S15B to detect the charging and discharging state of battery 11.The processing of step S15B is basically identical with the processing of step S15A.
When being judged to be just in motion (S12 of vehicle 10, no), car-mounted device 200 is carried out the user of vehicle 10 is sent the confined notice of part of functions of non-driving system Denso spare 13, the hand-off process of electric system and the driving processing (step S15B) of non-driving system Denso spare 13.
Because being under the motoring condition at vehicle 10, the processing of step S15B implements, the processing of this point and the step S15A that under idling mode, implements different, therefore, for example, as long as will limit to the user of vehicle 10 processing of part of functions of non-driving system Denso spare 13 or for motor vehicle processing that changes under motoring condition is processed in the driving of non-driving system Denso spare 13.Consider in the driving process of vehicle 10, compare with idling mode, the electric energy generated of alternating current generator 12 increases because of the rising of engine speed, therefore, the part of functions of non-driving system Denso spare 13 is alleviated to vehicle 10 users' restriction.
Processing by step S15B drives non-driving system Denso spare 13, detects after the level of charge in step S16, and flow process advances to step S17.
In step S17, for example, as long as it is not complete to be judged to be detection when occurring this situation that testing conditions changes the testing process at level of charge the situation about changing from motoring condition to idling mode such as vehicle 10.
Below, the processing of car-mounted device 200 execution in step S18～S20A or S20B.
When car-mounted device 200 finishes in the processing of step S20A or step S20B, finish a series of processing.
In addition, in step S19, when the state of the aging just very fast development of judging battery 11, for example, also the generation power of alternating current generator 12 preferentially can be offered driving system Denso spare 14.So, can make vehicle 10 drive to docking facility etc.In addition; at this moment; for example battery 11, alternating current generator 12, non-driving system Denso spare 13 and driving system Denso spare 14 are connected shown in Fig. 2 A; thus; can carry out to the power supply of non-driving system Denso spare 13 and driving system Denso spare 14 from alternating current generator 12; and, can protect aging battery 11 by also battery 11 being powered.When cutting off power supply, there are aging battery 11 irrecoverable possibilities, but can suppress battery 11 irrecoverable this situations by controlling like that as mentioned above electric power supply system with preventing trouble before it happens.
More than, according to the degree of aging decision maker 100 of embodiment one, in vehicle 10 operational processs (during idling mode or when travelling), by forcing to drive the electric power that non-driving system Denso spare 13 comes consuming cells 11.And, utilize the discharge of accompanying with the power consumption of battery 11 to measure level of charge, and judge degree of aging based on level of charge, therefore, can in vehicle 10 operational processs, grasp the degree of aging of battery 11.
Therefore, can very high degree of aging decision maker 100 and the car-mounted device 200 of facilitating property.In addition, so, owing to can in vehicle 10 operational processs, detect the degree of aging of battery 11, therefore, can suppress rapidly to improve because of the aging possibility that produces unfavorable condition of battery 11, can improve the reliability of vehicle 10.
And, owing to the result of determination of the degree of aging of battery 11 can be notified user to vehicle 10, therefore can provide the sense of feeling at ease to the user.In the case, if in vehicle 10 operational processs, judge degree of aging, and in vehicle 10 operational processs, result of determination notified user to vehicle 10, then can provide the sense of feeling at ease greatly to the user of the vehicle 10 in the operational process.
More than, to based on the congestion information that is obtained by step S13 by judging in step S14 whether the length of an interval degree that blocks up is illustrated to judge the mode whether idling mode continues at predetermined length.
But, the judgement gimmick of burst length of blocking up is not limited to above-mentioned gimmick, for example, also can constitute, (typical case, CCD(Charge Coupled Device: the vision signal that charge-coupled device) camera) obtains is judged interval the continuing of blocking up by the motoring condition of the vehicle 10 before and after monitoring based on the camera at the place ahead that is arranged at vehicle 10 and/or rear.
In addition, in the case, also can constitute, degree of aging decision maker 100 as remote monitoring center is collected many vision signals that vehicle 10 obtains, degree of aging decision maker 100 has or not the lasting no signal of having blocked up to be sent to car-mounted device 200 in the expression interval that blocks up, and it is lasting that car-mounted device 200 judges that based on the no signal of having blocked up the interval that blocks up has or not.
In addition, more than, the mode of vehicle 10 lift-launchs as the alternating current generator 12 of electrical generator is illustrated, but the degree of aging decision maker 100 of embodiment one and car-mounted device 200 also go for dynamotor (MG(Motor Generator)) replace alternating current generator 12 as the vehicle of the electrical generator of vehicle, lift-launch and alternating current generator 12 different modes of electrical generator.
As this vehicle, for example, can list hybrid vehicle (HV(Hybrid Vehicle) car), electronlmobil (EV(Electric Vehicle) car).

Then, use Fig. 6 to judging that by the degree of aging decision maker 300 of embodiment two processing that the degree of aging of battery 11 is used describes.
Fig. 6 is that expression is by the diagram of circuit of the contents processing of degree of aging decision maker 300 execution of embodiment two.In addition, as long as the judgement of the degree of aging of the battery 11 that degree of aging decision maker 300 carries out constitutes for example once so regular enforcement in per six months.
As shown in Figure 6, degree of aging decision maker 300 judges whether vehicle 10 is in idling mode (step S201).Under idling mode, because the speed of a motor vehicle is zero, so the speed that detects based on car speed sensor of idling mode detection unit 320 determines whether and is in idling mode.
When being judged to be vehicle 10 and being in idling mode (S201 is), degree of aging decision maker 300 obtains congestion information (step S202).Herein, congestion information acquisition unit 330 is obtained the VICS information of vehicle 10 working direction.
Then, degree of aging decision maker 300 judges whether idling mode continues (step S203).The processing of step S203 is carried out by lasting detection unit 340.
Continue the VICS information that detection unit 340 obtains based on congestion information acquisition unit 330, by judgement block up the interval whether at predetermined length to judge whether idling mode continues.
When being judged to be idling mode and not continuing (S203, no), degree of aging decision maker 300 turns back to step S202 with flow process.Thus, the repeatedly processing of execution in step S202, S203 continues until degree of aging decision maker 300 is judged to be idling mode.
(S203 when being judged to be idling mode and continuing, be), degree of aging decision maker 300 is carried out the user of vehicle 10 is sent the confined notice of part of functions of non-driving system Denso spare 13, the hand-off process of electric system and the driving processing (step S204A) of non-driving system Denso spare 13.
The confined notice of part of functions of the user of vehicle 10 being sent non-driving system Denso spare 13 will represent that by master control part 310 the confined information of part of functions of non-driving system Denso spare 13 is shown on the monitor 390, is shown on the monitor etc. of homing advice and carries out.The part of functions of non-driving system Denso spare 13 is limited such as being the volume of reduction acoustical equipment or the function of restriction homing advice etc.
The hand-off process of electric system is that relay 21～24(is with reference to Fig. 2 A, Fig. 2 B) hand-off process, when measuring level of charge, carried out by electrical path control part 360.
When detecting the degree of aging of battery, the driving of non-driving system Denso spare 13 is processed by 350 outputs of Denso spare drive division and is carried out for the driving instruction that drives non-driving system Denso spare.For example, when detecting the degree of aging of battery, in the situation that drives air-conditioning, Denso spare drive division 350 will drive the ECU that instruction is sent to air-conditioning, thus, drive air-conditioning with predetermined pattern (for example, defrosting mode).
The processing of step S204A is by execution the user of vehicle 10 to be sent the confined notice of part of functions of non-driving system Denso spare 13, the hand-off process of electric system and the driving of non-driving system Denso spare 13 to process to measure the processing that level of charge is used.
Then, degree of aging decision maker 300 obtains level of charge (step S205).The processing of step S205 is undertaken by level of charge acquisition unit 370.Level of charge acquisition unit 370 is obtained the level of charge of battery.
Then, the detection among the degree of aging decision maker 300 determination step S205 whether complete (step S206).
For example, in the testing process of the level of charge in step S204A, in the situation that vehicle 10 changes from idling mode to motoring condition, there is the possibility of the electric energy generated change of the power consumption of non-driving system Denso spare 13 or driving system Denso spare 14 or alternating current generator 12.Therefore, master control part 310 for example monitors the speed that car speed sensor detects, when occurring this situation that testing conditions changes the testing process at level of charge the situation about changing from idling mode to motoring condition such as vehicle 10, it is not complete to be judged to be detection, and flow process is turned back to step S201.
On the other hand, master control part 310 is when this situation that the testing conditions that level of charge do not occur changes, and it is complete to be judged to be detection, and makes flow process advance to step S18.
When the level of charge that is obtained by the level of charge acquisition unit during greater than threshold value, degree of aging decision maker 300 is judged to be battery 11 and is aged to and needs to change or cautious state (step S207).The determination processing of step S207 is carried out by degree of aging detection unit 380.
(S207 when the result of determination that is judged to be degree of aging detection unit 380 represents battery 11 aging, be), degree of aging decision maker 300 will represent to urge the information of warehouse-in to be shown on the monitor 390, and (step S208A) processed in the control change of the driving 10 of going forward side by side.It for example is the processing of the part of functions in the non-driving system Denso spare 13 of restriction that the control change of vehicle 10 is processed.When battery 11 wears out, be desirably in battery 11 close on the life-span (et out of order) before, safety and promptly vehicle 10 is moved to the docking facility or the place etc. of safety, therefore, by the load that the part of functions that limits in the non-driving system Denso spare 13 alleviates battery 11, allow to mobile state and prolong as far as possible.In addition, the part of functions in herein the non-driving system Denso spare 13 is limited to refer to the air quantity restriction such as air-conditioning, the volume limitations of acoustical equipment etc.
On the other hand, when being judged to be result of determination and not representing battery 11 aging (S207, no), degree of aging decision maker 300 will represent that the information of battery 11 intact (OK) is shown to (step S208B) on the monitor 390.Thus, do not need in the user of vehicle 10 can identify between short-term to change or cautious battery 11.
In addition, in step S201, be judged to be vehicle 10 and be not in the situation of idling mode (S201, no), degree of aging decision maker 300 makes flow process advance to step S204B.Being judged to be the situation that vehicle 10 is not in idling mode refers to: the speed of a motor vehicle is non-vanishing, and vehicle 10 is in the situation of motoring condition.
